It should be owned by root. If you look at the postinstall script in the
sendmail rpm, it even tries to fix this problem:
#
# Rebuild maps (next reboot will rebuild also)
#
{
chown
root /etc/aliases.db /etc/mail/access.db /etc/mail/mailertable.db \
/etc/mail/domaintable.db /etc/mail/virtusertable.db
/usr/bin/newaliases
for map in virtusertable access domaintable mailertable ; do
if [ -f /etc/mail/${map} ]; then
/usr/bin/makemap hash /etc/mail/${map} < /etc/mail/${map}
fi
done
} > /dev/null 2>&1
Removing the .db files and recreating them from the text files is the
safe thing to do.
